WHEEL `1VI1LL.

Application filed August 27, 1921.

which it appertains to make and use the same.

My invention relates in general to 1mprovements in the nconstruction ofwheel `mills which are adapted to roll metal car wheels or other similarannular bodies, but for the sake of convenience of description herein Iwill refer only to wheels.

I-Ieretofore mills of this character have had a framework formed of alarge number of parts, secured together `by bolting or othewise, thefront Aof which was .only bolted to the base plate forming' flexiblecantilevers, these and the other portions oll the structure carrying`the working parts,`

whereas I make a solid front framework connected at the top and bottomto the base and top framesto make a rigid construction.

lVith the prior constructions the springing or looseness of theframework allows the working portions to move from their proper' placesor out of adjustment, thereby spoiling the work, -and in addition tothis the prior constructions have been of such a character as'to requirea large amount of time and labor in making changes and necessaryadjustments of rolls. In order to obviate this I form the front portionof my apparatus substantially integral, tied together above and below,and mount upon it the working parts in such a way that the stresses ofuse are taken up by the solid front framework without the maladjustmentsabove referred to, thereby makinga compact and solid structure whichholds the working parts in position at all times.

Although I have shown my front `frame work as composed of vtwo sections,this is so drawn merely for the purpose of ease of making the castingsand machining the saine, and these two sections are held together -by avery few bolts, and when the front frame so composed is secured togetherand to the other parts of the framing it is substantial- 5 ly integral.

Serial' No. 496,124.

I may, however, make the front frame completely integral and omit theflanges, separator and bolts which secure the two halves together, thusmaking it entirely integral and in one piece and well adapted towithstand the stresses and strains of use.

In addition, my construction is of a simple character andmy frontframework, comprising front apron and headblock portions, is secured tothe other parts, such as the rear frame and the base plate, byquick-acting bolts, so that it can be disassembled for replacement andadjustment ofthe working parts and reassembled in one-third the timethat is required with the old'structures.

Vith the Told structures any movement of the headblocks or similarportions lin relation to each other or to the working portions, such asweb rolls, back or tread rolls, or guide rolls will cause the wheelwhich isr being rolled to become nonuniform in dimensionsand inconsequence it is rejected and is only scrap, whereas with myconstruction the working parts are held so firmly in position that thesetroubles are entirely obviated.

In prior constructions the minor in and out adjustments of the edgingrolls were ob- Vtainedby mounting them on eccentric pins,

which pins when rotated slightly move these rolls inwardly or outwardlyas desired, but this adjustment was insuflicient and shims were requiredto line the brackets of the edging rolls, necessitating much loss intime and labor. This construction has been improved by me whereby Imount the edg- I ing rolls on adjustable Shanks with screw movement ofsuiicient extent vfor all adjustments longitudinally.

Another difficulty with the prior type of edging rolls is the fact thatin rolling wheelsV of different diameters the edging rolls werenon-adjustable in a direction approximately radial to the wheel, withthe result that with wheels of different diameters the angularity of theaxes of the edging rolls caused pulling and tearing action on the wheelrim, which distorted the wheel and produced slivers on it. I obviatethis difliculty by mounting my edging rolls so that their axes can beadjusted with respect to the radius A of the wheel, the rim of which isthereby rolled approximately on circumferential lines, thus obviatingthe destructive action above mentioned, and lthis avoids the draggingand consequent slivering of the wheel rims.

In addition to this the edging rolls are not required to be the samedistance apart from the center line for all wheels on account of thevaried design of different wheels, and my method of separately adjustingthese edging rolls applies itself readily to this requirement.

In my construction the right and left hand sections of thefcombinedheadblocks and apron forming the front frame are substantially integralvwith each other, and theirfrelations to each other and other portionsare such as to firmly maintain them in position and thereby hold theworking portions mounted therein in rigid adjustmentas desired, and theheadblocks or aprons each have integral pads on which the wheel mandrelrest-s and these are integral .withthe.framework which carries the edg-.ing and guide rolls.

The front-apron, which comprises the headblocks and wheel j mandrelsupports, supports the edging rolls withtheir adjusting mechanism andcarries the guid rolls, is incorporated substantially as one unit, so

l thatit may be easily, quickly and securely Y attached to or detachedfrom the top and bottom plates of the mill frame, which j therebyreduces the time necessary to change the'working parts and insuresproper relai tive alignment thereof.

-In addition to the difficulty of fslivering the rims and thedestruction ofthe metal of the wheel in prior practice, my adjustment ofthe edging rolls to the substantially radial position of their axes withrespect to the wheel, also eliminates excessive wear on theedging rollsin addition to 'preventing slivering due to their` incorrect position.

- Having thus givenl a general description lof my invention, I will now,in order to .make the matter morey clear, refer to the annexed twosheets of drawings, which form part of this specification, and in whichlike characters refer to like parts.

Figure 1 is a side elevation of my improved wheel mill; Figure 2 is avertical o sectional elevation of the apparatus taken on the line II-IIof Figure 1; Figure 3 is a detail view showing` the mounting of one -ofthe idler gears which meshes with a pinion on the drive shaft and a gearon the shaft of the adjusting screw for advancing or retracting the edgeroll brackets; Figure 4 is a detail view of the indicator dial; Figure 5is a detail view illustrating the position of the web` and tread rollswhen in operation; Figure 6 is avertical ylongitudinal sectionalelevation of one of the edge rolls, the edge roll bracket for holdingthe same, and the adjusting means for the edge rolls; Figure 7 is ahorizontal longitudinal sectional elevation of the mechanism shownerence on the drawings: 1 indicates the rear framing of the mill ingeneral; 2 are the slideways thereof upon which the tread or back r'illis mounted; 3 is the tread or back roll; 4 is the front frame or headblock composed of two sections, having the mandrelA supports integrallycombined with the other portions thereof. The right and left handsections of these portions 4 are secured together by the bolts 5 and 6,which latter are provided with separators or spacers 7 as illustrated.`S are keys or projections between the main f ame and the headblock 4adapted to hold these parts in proper relative position. 9 is thesupport and guideway for the arbor or mandrel on which the wheel inprocess of rolling is held, formed integral with the frame 4; 10 arewearing plates `or shims in the guideway for supporting the arbor andmore or less of these are used or they may be of different thicknessesand removable and replaceable to accommodate wheels of different sizesand diameters; 11 is the mandrel or arbor on which the wheel and blankis mounted during the process of rolling. 12 indicates the wheel blank,which is of smaller diameter than the finished wheel, in position forrolling and 13 are the edging rolls which operate upon the rim of thewheel and are adjusted inwardly and outwardly and to radial position.'14 are the shafts on which the 105 edging rolls are rotatably mounted;15 are brackets which support the edging roll shafts; 1.6 are the shaftsor adjustable shanks of the edging roll brackets adapted to rbe adjustedinwardly or outwardly or rotated within their supports to produce theradial position of the roll axes as desired. 17 are sleeves mounted on16; 18 are sockets in portions of the headlock or front frame 4 whichreceive the sleeves 17. 19 is a feather H5 key slidably connecting theportions 16 and 17; 2O is a nut mounted in the shank 16,

'which, in connection with the adjusting screw 21 and attachments isadapted to feed the shank inwardly or outwardly to adjust l?" the edgingrolls as necessary; 22 is a collar on the screw 21` to withstand thethrust thereof and on the extending end portion 23 of the screw 21 ismounted the gear 24. 25 is a pipe for feeding grease or lubricating oilto the moving portions. -A flange 26 is attached to or part of theadjusting sleeve 17, in which are formed a number of bolt holes 27 asillustrated, through which bolts 28 are passed in order to secure theparts in 130 the rela-tion desired. 29 is a flange on part ot the milltraining which also has a series et holes therein. These holes in theiianges 2G and 29 are in staggered relation with more holes in oneportion than in the other, so that by moving the parts one hole registers With another hole and the holt inserted so that adjustment can bemade ot the edging rolls 13. By means ot this adjustment, the axes ofthe edging' rolls can he set within tivo or three degrees. 'lhe flange26 is provided with a socket 30 in which a bar can be inserted to rotateit as desired for adjustment. The shank 1G is mounted in the bushing 17in suoli a manner that it may be moved endivise therein, and hy reasonof the feather it can he rotated vfith the bush ing 17. Integral bosses31 are also provided, in which are mounted stud bolts 32 provided withcollars 33 and on which the idler gears 34 are mounted and secured,these being arranged to gear with the pinion on the drive shaft 3G. Thestud bolts 32 are provided with Washers 37 on their outer ends asillustrated. 3S is an indicator dial adapted to show the position et'the edging rolls, which dial may be graduated temporarily Afrom time totime to suit the ivorlr. This dial is provided with an indicator handSi) mounted on the cylindrical projection The drive shaft is providedwith driving gear generally indicated as 41, operated by the motor 43geared thereto. are the web rolls which are converging and tapered asillustrated and provided with driving means (not shown).

Referring now to Figure 9, vvliioh shows an alternate arrangement otadjustment tor the edging' rolls z-this is provided with journalhearings 44, in which is mounted a Worin 45, provided vwith a manuallyoperated crank a-rin The sleeve 17 is provided with a flange 47 formedas a sector oi a `worin wheel and provided with ina "ginal teeth 4Gwhich engage ivitli the thread of he Worm gear 45. 47 may also beprovided ivith slight corrugations 48 and corresponding corrugatedivashers 49, which, when the sleeve 17 is adjusted by means ot thecranlr frm 52, can be securely clamped in place by means ot the bolt 50,the corrugated Washers 49 and the oorrugations et the 'flange 47. Theflange 47 is also provided With a curved slot 51 through which the bolt50 is passed. By means of this mechanism l can adjust the radialposition of the edging rolls to the traction of a degree.A Thecorrugations may be omitted it desired. v

Thelwheel after or during rolling is 53, as shown in dotted lines, otexpanded diameter greater than the blank due to rolling` thereof', andmy apparatus is iur-ther provided with guide rolls 54, and in Certaincases only one oi these may be needed, but in other cases two may beused as illustrated,

these guide rolls being mounted in l the brackets 55, 'which carry thepivot support ing bolts 56. 57 are loolts which secure my iii'iprovedfront `trame to the other parts et the training and lor the purpose otrapidly removing the trame and changing rolls some ot these bolts havetheir heads introduced into T-slots, so that a slight turn on the nutswill allow them to he slid in and out ot position in the slotted lugs,While other bolts may have eye heads Yon pivot lxolts, around which theymay be turned 'when the nuts are loosened, and others are usualthrough-bolts requiring, however, only the screwing or unscrew'ing ot anut with a teiv threads so that all are quick-acting tasteniiigs, and asll have only tori bolts which secure the entire trent trame to the otherstructure, the liront trame very easily loosened and talceii aivay fromthe other parts and as ea y secured in place ag .lo talco oli' the ironttraine l slide the couj 'ig' to the lett, loosen or take otli' the nutstrom the bolts rotate er slide some et the ten holts 57 and then removethe :trout trame and the reverse operation will install it in placeagain. ily means oiI my construction l can make the change in one-third'the time previouslv refpiired.D
